Given numbers are 304, 390, 742, 115

The list of prime factors of all numbers are

Prime factors of 304 are 2 x 2 x 2 x 2 x 19

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 742 are 2 x 7 x 53

Prime factors of 115 are 5 x 23

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 304, 390, 742, 115

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(304, 390) = 59280

GCD(304, 390) = ( 304 x 390 ) / 59280

= 304 / 390

= 304

Step2:

LCM(2, 742) = 742

GCD(2, 742) = ( 2 x 742 ) / 742

= 2 / 742

= 2

Step3:

LCM(2, 115) = 230

GCD(2, 115) = ( 2 x 115 ) / 230

= 2 / 115

= 2

So, Greatest Common Divisor of 304, 390, 742, 115 is 1
